History of Hà Nội

Hà Nội History & Heritage Guide 2026

The history of Hà Nội told through its places: sites worth the detour and the context they need.

Hà Nội has 10+ historical sites covered in this guide, led by Imperial Citadel of Thang Long (UNESCO), Temple of Literature and Imperial Academy and Hoa Lo Prison. Each entry below includes the practical details — what it costs, when to go, and how to plan around it.

Hà Nội (Hanoi) is the capital of Vietnam and its cultural heart, a city of lakes, tree-lined French colonial boulevards, and a thousand-year-old Old Quarter where every street once specialised in a single trade. Visitors come for street food such as phở and bún chả, egg coffee, water puppet theatre, temples and museums, and easy access to Hạ Long Bay, Ninh Bình, and the northern mountains.
